I have for sale a very clean Conrad Johnson MF-2300 power amp. in perfect working order. Never been modified or serviced. Comes with original box and packing. But no manual. Will be double boxed for safe delivery. only has one small hairline scratch on the top. about 3/8 inch long. Very hard to see. Very minor. The rest is beautiful. I would rate this as a solid 9 out of 10. But as per Audiogon guidelines. I will rate it as an 8. As Audiogon sates a 9 has zero scratches.
